2025 GMC Sierra 2500 SLT review
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

I had an amazing car buying experience with Sam at John
I had an amazing car buying experience with Sam at John Miles Chevrolet! From start to finish, he was absolutely phenomenal. It had been over a decade since I last purchased a vehicle, so I was feeling a bit overwhelmed, but Sam made the entire process smooth, clear, and completely stress-free. He kept me in the loop every step of the way, especially about when the car would arrive in-state, and made sure I understood each part of the buying process. No pressure, no confusion?just honest, helpful guidance and great customer service. If you're looking for someone who?s knowledgeable, patient, and truly cares about helping you find the right vehicle, Sam is your guy. I couldn?t be happier with my experience!
